Patent No. 291,182, dared January 1, 1854.

Applicationniled August 24, 1883. (No modem To all whom it may concern.-

Ee it known that I, DAVID B. Gaaroma subject of the Queen of Great Britain, and a citizen of Canada, residing at Barrie, in the Province of Ontario, Canada, have invented certain new 'and useful Improvements in Snow- Blows for Railways, of which the following is a specification.

My invention relates to that class of snowplows which are carried by the locomotive and forward of the'same, in which an inclined shovel having at its outer sides parting-blades,

made with a mold-board form, and intermediate slicing or stripping blades, also made with a mold-board form, co-operate together to separate and part the snow on the railway-track from the snow at the sides thereof, and also divide the snow'on the track into slices or strips, to be carried upwardly, and throw the same outward on the sno-w at one or both sides of the track, accordingly. as the track to be cleared is a single or double track, and the plow is made to be a single-side or double-side clearing-plow. 1

The objects of my invention are to provide means by which the snow on the track will be separated from the snow at the sides thereof,

f and be out into strips, and the strips of snow thus formed be elevated and thrown outward is a horizontal vi'ew, from above, illustrating a single track plow. view.

Fig. 3 is a front end Fig. 4 is a rear end view. Fig. 5 is a horizontal yiew, from above, of a double-track plow. Fig. 6 is a front end view, and. Fig. 7 is a rear end view.

In the drawings, A represents the shoe of theplow, which shoe is made, preferably, Vof stiff plate metal-such as boiler plate-iron or plate-steel--and with a width a little greater than that of the track from which the snow is to be cleared. In plows intended to clear snow from a railway having a single track, l make the shovel portion of the same to incline in one direction, upward and rearward, as shown in Fig. 1, and with its two halves or side portions, a a, to incline in opposite directions from a line through its middle of width downward and outward to the sides thereof, as shown in Figs. 2, 3, and 4. These inclined sides of the shovel portion of the plow are also made of stiff plate iron or steel. Securely bolted or riveted to the said inclined half portions of the shovel, at their outer edges, are the parting-blades B B, which blades are also .made of stiff plate iron or steel. The forward Vand lower ends of these parting-blades are preferably made to incline slightly outward, as shown in Fig. 3, though they may be made to be substantially vertical. Said partingblades have a vertical extension of about from fifteen to twenty inches, more or less, as may be deemed sufficient to cnt through that or a less or greaterdepth of snow. rlhese blades are made to run upwardly and rearwardly, with a gradual outward curving of the same until they lie at their rear ends about hori- Zontal, as shown in Figs. 2, 3, and 4, and project over the side edges of the shovel to a distance-about or nearly equal to their width.

Securely bolted or riveted to the inclined diate between the partingblades B B, are a series of slicing or stripping blades, O O, which also are made of plate metal. These stripping or slicing blades are made with a vertical ex tension of width about equal to that of the parting-blades B B, and also are made to have a mold-boardi'orm, by being each gradually curved over the next lower neighboring blade, as shown. The channel formed between each of two neighboring blades, as between blades AB and C, or blades C and C, operate to conduct the snow in strips, each in a separated manner, from the snow at the sides of the track and from each of the other strips, and deliver the same at the sides of the plow on the snow at the sides of the track.

In a double-track snow-plow I ina-ke the side portions, a a, of the shovel, and interme- IOO shovel portion a of the slice inclined upwardly and rearwardly, as shown in Fig. 1, and also make it to incline from one of its side edges upwardly and laterally to the opposite side, as shown by dotted and full lines in Figs. 5, (i, and 7. By this manner of inclination of the entire shovel-portion of the plow, the snow worked up on the oi'tl side surface ot' the shovel will be more elevated than that worked up on the nigh side, or the side the entire bodyof the track-snow is to be delivered. Securely bolted tothe lowside edge and to the elevated side edge of this shovel, by bolts or rivets, are

the parting-blades B B, which parting-blades.

are made of stiffplate metal, and with a width or vertical extension (in iront) ot' about fifteen to twenty inches, more orless. rl`he partingbladeB on the lower side edge ofthe shovel isr nrade to gradually turn or curve outward with 1a mold-hoard i'orm as it runs rearward. The parting-blade at the opposite side edge, or higher edge, is made to turn or curve in the sature direction, or toward the lower side parting-blade, as shown in Figs. 5. (5, andl 7.

Securely attached to the inclined shovel, by boltsor rivets, are the intermediate slicing or stripping blades, C, which are cach made with about the same width as the parting-blades, and are in like manner gradually turned or curved over toward the lewerside edge of the shovel, with a mold-board forni substantially the saine as the parting-blades, so that all the blades, both the parting and intermediate slieing-blades, will have their mold-board portions, turn or curve in direction of the lower ,side edge ofthe inclined shovel.

XVith this i'orm o1' construction and arrangement of parts in the modification shown in Figs. 5, 6, and 7, the snow on the track will be parted i'roni the snow at the sides ot' the track, and will be gradually elevated as the plow is carried forward by the locomotive, and be eut into strips, which strips will have an upward passage through the channels from between each two neighboring blades, and the snow, will be delivered in its entire body at oneside ofthe track.

This 'double-track plow may be made to throw the snow to the right-hand side or the left-hand side, so that on a double-track railway the snow may be thrown out and off the two' neighboring tracks on the oft side of the same.

In the operation ot' my improved snowplow, whetherit be a single or double track plow, the packing and wedging together of the snow on the track with that on the sides thereof, as heretofore, is wholly avoided, and the loeonlotivc will be enabled to run with a speed of from twelve to twenty miles per hour, and clear the track of snow in a rapid and comparatively easy manner, and without making stoppages, as heretofore required.

Having described my i nvention, whatI el aim and desire to secure by Letters Patent, is*q l. In snow-plows for railways, the combination, with the angular or inclined sides of shoe A, of the oppositely-loeated and ver-tr cally-arranged parting-blades B B, which have each their upper marginal portions inclined and made to curve outwardly with a gradually-inercasing extension of lateral projeetion of said margin portions as they are made to run upwardly and rearwardly, sub- A stantially as and for the purpose set forth.

2. In snow-plows for railways, the combination, with the oppositelyinclincd sides a a 'ot' shoe A, and the vertieally-arranged parting-blades B B situated at the outer sides o1'l said shoe, and made to have their upper niarginal edge portions extended outwardly with a graduallyinereasng curve as they run rearwardly and upwardly, ot a series ol' one or more intermediate and verticallyarranged slicing-blades, which have a gradually-increasing vertical extension above bladesB B, and outward]y-curved and laterally-projecting marginal portions, which gradually increase in the outward throw ot' curve as said curved portions run upwardly and rearwardly, substantially as and ior the purpose set forth.

3. ln a snow-plow l'or railways, the combination, with shoe A, having oppositely-inclincd sides, of the verticallyarranged outer side parting-blades, B B, and the series of verf tically-arrangcd slicing-blades situated intermediate between said parting-blades, and having a gradually-increasing vertical extension above the said parti iig-blades as they run rearwardly and upwardly, all suliistantially as and for the purpose set forth.
